A major drawback of a typical three transistor (3T) pixel circuit is high thermal (e.g., kTC) noise, which deteriorates dynamic range and low light performance. The 3T pixel kTC noise depends on pixel conversion gain. Unfortunately, a high-conversion gain results in the both poor dynamic range and low signal-to-noise ratio (SNR) at high light. Considerations in the prior art included proposals to reduce kTC noise with feedback amplifiers and parametric resets of detection nodes incorporating voltage dependent capacitor components. The feedback amplifier approach requires significant additional power. Speed is limited by a slow ramping of reset voltage. The parametric reset with voltage depend capacitor has never, to date, actually been implemented. Further, some persons of ordinary skill in the art have expressed concern about the feasibility of this approach. Moreover, a proposed dual conversion gain pixel can improve only inter-scene dynamic range. Additionally, a proposed overflow principle for four transistor (4T) pixel dynamic range extension requires multiple readout paths and off chip processing.
